What are the causes of excessive water temperature in diesel engines?

[KingLee]

Diesel engine water temperature is too high caused by: lack of coolant or improper selection, insufficient heat dissipation area, thermostat failure. Lack of coolant or improper selection: Cannot remove the heat generated by engine parts in time. Coolant is an indispensable part of automobile engines, consisting of water, antifreeze and additives. It circulates in the engine cooling system to remove excess heat generated during engine operation, ensuring the engine operates at normal working temperature. Insufficient heat dissipation area: The heat dissipation area of cooling water for diesel engines is matched according to power and load. Since the coolant for water-cooled diesel engines is mostly composed of water and ethylene glycol, unqualified coolant quality can produce a large amount of scale in the heat dissipation pipes, blocking them and reducing heat dissipation efficiency. Thermostat failure: Automatically adjusts the amount of water entering the radiator according to the temperature of the cooling water. Changes the circulation range of water to regulate the heat dissipation capacity of the cooler, ensuring the engine works within a suitable temperature range.
